Additional Tractor Unit

You can improve the performance of continuous paper handling by
using two tractor units at the same time. An additional tractor unit
is available as an option. This is especially useful for continuous
pre-printed forms, multi-part forms, and labels. Use of two tractor
units at once is also recommended to print the highest quality
graphics.
Also, if you install the tractor units in the front and rear push-
tractor positions, you can load two types of continuous paper at
the same time and switch between them by moving the paper-
release lever.
